Plasma nitriding is a smart choice whenever parts are required to have both nitrided and soft areas. Material. Plasma nitriding allows faster nitriding times, and the quickly attained surface saturation of the plasma process results in … The corrosion resistance of the steel in 0.05 M Na2SO4 at pH 3 decreases as a result of nitriding. Recommended Core Hardness Plasma Nitrided Surface Hardness Total Case Depth (inches) 1020, 1045, Cast Iron: 14-8: File Hard 0.0005' 0.002-0.010: 8620, 9310, 9315, P6: 14-8: 52-58: 0.012-0.028: 4130, 4140 Plasma nitriding technology When the hardness difference between substrate and coating causes performance loss, plasma nitriding may be the solution. Ionitriding (Plasma), or Glow-Discharge Nitriding: It is a case-hardening process of enriching the surface of the steel with nascent nitrogen by glow discharge method. The location of the low-temperature carburized layer was pushed ahead following nitriding to form a support layer for a hard nitrided surface layer. To that end, nitriding, and nitrocarburizing, have been the surface treatment of choice for decades. Plasma nitriding can be used for hardening long parts, such as this steel shaft, because it delivers a uniform diffusion of nitrogen along the entire part. The basic technological advantage of this method is the low temperature at which the process is conducted, resulting in very small dimensional changes. : +49 2401 8097-0 been established that nitriding markedly raises the wear resistance of the steel at pressures of 50, 200, and 400 MPa. Plasma nitriding (ion nitriding) is a plasma-supported thermochemical case hardening process used to increase wear resistance, surface hardness and fatigue by generation of a hard layer including compressive stresses. The advantage is that a low process temperature of about – or under – 500° C is well suited for plasma nitriding and there is thus no drop in the core hardness of hardened steel. After nitriding at 785°C the proportion of these phases is minimal. Plasma Nitriding Plasma nitriding (also known as ion nitriding, plasma ion nitriding or glow-discharge nitriding), is an industrial surface hardening treatment for metallic materials. This treatment is carried out in the temperature range where α iron exists in the iron-carbon phase diagram. The hardness achieved on the surface decreases with depth until the core hardness is reached. In plasma nitriding, the reactivity of the nitriding media is not due to temperature but to the gas ionized state. Plasma ION nitriding is an industrial surface hardening treatment for iron-based materials. With today's highly engineered parts, designers are increasingly turning to advanced plasma nitriding for more precise control of the diffusion layer formation, depth of hardening, and preservation of component dimensions. It is the most technically superior of all nitriding processes and has many advantages compared to traditional salt bath and gas nitriding. Nitriding is usually done by heating steel objects in gaseous ammonia (NH3) at temperatures between 500 and 550 Hardness Chart Typical Plasma Nitriding Results. The processes are named after the medium used to donate. The low temperature plasma nitriding behaviour of 17-4PH type precipitation hardening stainless steel was investigated in the present work. The result of the plasma nitriding or plasma nitrocarburising process is increased surface hardness and wear resistance, lower wear coefficient, increased fatigue resistant, ductility, increased corrosion resistant, resulting with many times increased tool life of the machine parts or tools. The advantages of gaseous nitriding processes can be surpassed by plasma nitriding. We perform advanced case hardening on a wide variety of steels. Depending on the layer thickness and surface hardness, testing is performed with a variable load. nitriding were developed using the carbon push-ahead effect of nitriding using relatively low-temperature plasma treatment.
